Dual slider stop



March 30, 1965 L. H. MORlN DUAL SLIDER STOP Filed Oct. 25, 1963 INVENTOR. Lou/5 h. MoR/N BY A TTURNEY' United States Patent 3,175,268 DUAL SLIDER STOP Louis H. Morin, 125 Beechwood Ave., Bronx, NY. Filed Oct. 23, 1963, Ser. No. 318,212 3 Claims. (Cl. 24205.11)

This invention relates to separable fasteners employing a pair of stringers, wherein each stringer has, at one common end thereof, interlocking pins arranged adjacent end scoops of the stringers and, further, wherein a pair of substantially similar sliders are movable along the stringers to couple and uncouple the same so that a pair of stringers can be coupled and uncoupled at opposed end portions of the stringers and, still further, wherein the one stringer can be completely detached from the other stringer when both sliders are arranged adjacent each other at the pin end portions of the stringers.

More particularly, the invention deals with a fastener structure of the character described, wherein the pin of one stringer and one of said sliders have interengaging means, preventing displacement of both sliders from said one stringer.

Still more particularly, the invention deals with a structure of the character defined, wherein the pin of the detachable stringer includes an integral scoop portion recessed to receive projecting portions on adjacent scoops of the companion stringer when the pin end portions of the stringers are in coupled relationship to each other.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

FIG. 1 is a sectional view through a pair of sliders arranged at pin end portions of a pair of stringers and diagrammatically illustrating coupling and uncoupling of one of the stringers with the companion stringer, the bead and scoops only of each stringer being shown to simplify the illustration.

FIG. 2 is a view, similar to FIG. 1, showing the sliders in spaced relationship to each other in illustrating the two stringers in coupled relationship to each other, with part of the pin of one stringer shown in section.

FIG. 3 is an inverted view, otherwise generally similar to FIGS. 1 and 2, partially illustrating the movement of the normally lower slider into position separating the two stringers.

FIG. 4 is an enlarged perspective detail view of the scoop end portion of the pin of one stringer; and

FIG. 5 is a detail section on the line 5-5 of FIG. 2.

In order to simplify the illustration and to show the slider structures in full lines, the stringer tapes of the two stringers employed are omitted and the bead portions only of the tapes are illustrated. The bead of one tape is shown at ill and the bead of the other tape is shown at 11 in FIGS. 1, 2 and 3. However, in FIG. 4, it will appear that part of the tape of the bead 11 is indicated at 11'. These stringer tapes are well-known in the art and, by omitting the tapes, a clearer understanding of the invention will result and, as with other fasteners, the beads and tapes extend into the pin 12 of the stringer bead 1t) and the pin 13 of the stringer bead 11, the pins 12 and 13 being crimped onto or otherwise fastened upon the beads and adjacent portions of the tapes. At 14 and 15 I have shown scoops applied to the beads and 11, the end scoop 14 being arranged adjacent the inner end of the pin 12; whereas, the end scoop is spaced with respect to the inner end of the pin 13. The inner end of the pin 13 has an integral scoop part 16, generally of the contour of the coupling end portions of the other scoops, the scoop part 16 being recessed,

as seen at 17, FIGS. 2 and 4, to receive projecting nubbins 13 on the scoop 14 and the adjacent scoop 14", as clearly indicated in FIG. 2 of the drawing. It will also appear, from FIGS. 1 and 4, that the scoop part 16 includes nubbins 1? engaging the scoop 14', 14". At 20 is shown what may be regarded as the upper or normal slider and at 21 is shown the associate dual slider, both sliders having spaced walls joined at the wide end thereof in an integral connecting web, as at 22 on 29 and 23 on 21. The slider 21 differs from the slider 20, in that the wide end portion includes side recesses on inner surfaces of the walls of the slider, which recesses form shoulders 24 adapted to engage laterally projecting stop lugs 25 on the outer end portion of the pin 12, as clearly illustrated in FIG. 5. This construction retains both sliders 2t 21 against displacement from the stringer, including the head 10; whereas, the stringer having the bead 11 with the pin 13 thereon is free to move into and out of the dual sliders when in the position shown in FIG. 1 in completely separating the two stringers and reassemblage of the stringers by insertion of 13 into the dual sliders, as diagrammatically shown.

After assemblage has been made, the: slider 21? is movable along the stringers to couple the same and this slider will control opening and closing of the stringers at one end thereof, where the slider 2t operates in conjunction with the usual stops that are employed. With this construction, it is also possible to move the slider 21 along the stringers, as indicated, in part, in FIG. 3 of the drawing in separating the end portion of the stringers having the pins 12, 13 thereon. In this manner, a separable fastener can be opened at both ends as and when desired and to any degree desired.

In the viewing of the two sliders 20, 21 in FIGS. 1 and 2 of the drawing, one wall only of the slider is shown and it will appear that the slider 20 has side flanges 26 and the slider 21 has similar flanges 27 for engaging the scoops, as well as the pins in the several operations of the fastener. The associated slider walls can include similar flanges.

In FIG. 5 of the drawing, part of the tape of the bead 10 is indicated at 10, similar to the showing of the tape portion 11' of FIG. 4 and, as previously stated, the illustration of the tape of each stringer has been omitted from the showing in FIGS. 1, 2 and 3 in order that the sliders can be shown in full lines.

In forming the integral scoop part 16 on the pin 13, the pin is also fashioned to form a socket portion 28 inwardly of the part 16, as clearly shown in FIG. 1, this part being fashioned to receive the coupling head of the scoop 14' when the pins 12, 13 are coupled together, as seen in FIG. 2. The scoops 15 also include nubbins 18, similar to the nubbins on the scoops 14, which operatively engage the scoops 14, similar to engagement of 18 with the scoops 15 in securely coupling the scoops of the stringers against separation, as with other scoop structures of this type and kind.

It will appear from a consideration of FIGS. 1, 2 and 3 of the drawing that the pin 13 is contoured for passage through the slider 20, as well as into and through the slider 21 in the several uses of the fastener. Further, by providing substantially similar sliders, the channels of the sliders aline one with the other when in abutting engagement, as clearly illustrated in FIG. 1. As previously pointed out, the illustrations in the several views are diagrammatic.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A separator structure of the character defined comprising two substantially similar sliders, each slider having a pair of spaced walls joined and spaced at wide ends in a connecting web, the walls of the sliders having flanged sides alined one with the other when the sliders are in abutting engagement so that channels of both sliders are in common alineinent when the sliders abut, the inner surfaces of the Walls of one slider being recessed at the Wide end portion thereof to form stop shoulders, stringers having scoops on beaded edges thereof coupled and uncoupled by both of said sliders, beaded edges of said stringers having at one common end projecting pins, the pin of one stringer having; at its free end projecting lugs operatively engaging the shoulders of one slider in retaining both sliders against displacement from said one stringer, the pin of the other stringer having at its inner end an integral scoop part and adjacent socket portion having an opening at least as wide as the head of the scoop on the opposite stringer which engages in said socket portion When the stringers are coupled together, said scoop part operatively engaging a pair of end scoops on the first named stringer when the stringers are in coupled engagement with each other, and both of said sliders being adapted to independently separate end portions of the stringers.

2. Astructure as defined in claim 1, wherein the scoops of both stringers include projecting nubbins, and said 4 scoop part of the secondnarned pin being recessed to receive nubbins on the end scoops of the first named stringer.
